Hi ,

i run RAILS\_ENV=‘production’ rake db:migrate , script/server -e  
production, i can successfully run in production environment now.  
But when i wanna go back to development mode with rake db:migrate ,  
script/server , something goes wrong. It seems, can’t find the  
database?

Any one have met this problem ?

Are you sure you have not changed something? Having run in production  
mode should make no difference.

What is the exact error you get on rake db:migrate?

Also show us config/database.yml please.
